     The compounds may be prepared as pharmaceutical compositions, and may be used for the prevention and treatment of a variety of conditions in mammals including humans, including by way of non-limiting example, diseases involving cartilage degradation, bone and/or joint degradation, for example osteoarthritis; and/or conditions involving inflammation or immune responses, such as Crohn&#39;s disease, rheumatoid arthritis, psoriasis, allergic airways disease (e.g. asthma, rhinitis), juvenile idiopathic arthritis, colitis, inflammatory bowel diseases, endotoxin-driven disease states (e.g. complications after bypass surgery or chronic endotoxin states contributing to e.g. chronic cardiac failure), diseases involving impairment of cartilage turnover (e.g. diseases involving the anabolic stimulation of chondrocytes), congenital cartilage malformations, diseases associated with hypersecretion of IL6 and transplantation rejection (e.g. organ transplant rejection) and proliferative diseases.

FIELD OF THE INVENTION

The present invention relates to compounds that are inhibitors of JAK, a family of tyrosine kinases that are involved in the modulation of the degradation of cartilage, joint degeneration and diseases involving such degradation and/or inflammation. The present invention also provides methods for the production of these compounds, pharmaceutical compositions comprising these compounds, methods for the prevention and/or treatment of diseases involving cartilage degradation, bone and/or joint degradation, conditions involving inflammation or immune responses, endotoxin-driven disease states, cancer, and organ transplant rejection; and/or methods for the prevention and/or treatment of diseases involving cartilage degradation, joint degradation and/or inflammation by administering a compound of the invention.

Janus kinases (JAKs) are cytoplasmic tyrosine kinases that transduce cytokine signaling from membrane receptors to STAT transcription factors. Four JAK family members are described, JAK1, JAK2, JAK3 and TYK2. Upon binding of the cytokine to its receptor, JAK family members auto- and/or transphosphorylate each other, followed by phosphorylation of STATs that then migrate to the nucleus to modulate transcription. JAK-STAT intracellular signal transduction serves the interferons, most interleukins, as well as a variety of cytokines and endocrine factors such as EPO, TPO, GH, OSM, LIF, CNTF, GM-CSF, PRL Vainchenker W. et al. (2008).

The combination of genetic models and small molecule JAK inhibitor research revealed the therapeutic potential of several JAKs. JAK3 is validated by mouse and human genetics as an immune-suppression target (O'Shea J. et al. (2004)). JAK3 inhibitors were successfully taken into clinical development, initially for organ transplant rejection but later also in other immuno-inflammatory indications such as rheumathoid arthritis (RA), psoriasis and Crohn's disease (http://clinicaltrials.gov/).

TYK2 is a potential target for immuno-inflammatory diseases, being validated by human genetics and mouse knock-out studies (Levy D. and Loomis C. (2007)).

JAK1 is a novel target in the immuno-inflammatory disease area. JAK1 heterodimerizes with the other JAKs to transduce cytokine-driven pro-inflammatory signaling. Therefore, inhibition of JAK1 and/or other JAKs is expected to be of therapeutic benefit for a range of inflammatory conditions as well as for other diseases driven by JAK-mediated signal transduction.

BACKGROUND OF THE INVENTION

Cartilage is an avascular tissue of which chondrocytes are the main cellular component. The chondrocytes in normal articular cartilage occupy approximately 5% of the tissue volume, while the extra-cellular matrix makes up the remaining 95% of the tissue. The chondrocytes secrete the components of the matrix, mainly proteoglycans and collagens, which in turn supply the chondrocytes with an environment suitable for their survival under mechanical stress. In cartilage, collagen type II, together with the protein collagen type IX, is arranged in solid fibril-like structures which provide cartilage with great mechanical strength. The proteoglycans can absorb water and are responsible for the resilient and shock absorbing properties of the cartilage.

One of the functional roles of cartilage in the joint is to allow bones to articulate on each other smoothly. Loss of articular cartilage, therefore, causes the bones to rub against each other leading to pain and loss of mobility. The degradation of cartilage can have various causes. In inflammatory arthritides, as rheumatoid arthritis for example, cartilage degradation is caused by the secretion of proteases (e.g. collagenases) by inflamed tissues (the inflamed synovium for example). Cartilage degradation can also be the result of an injury of the cartilage, due to an accident or surgery, or exaggerated loading or ‘wear and tear’. The ability of cartilage tissue to regenerate after such insults is limited. Chondrocytes in injured cartilage often display reduced cartilage synthesizing (anabolic) activity and/or increased cartilage degrading (catabolic) activity.

The degeneration of cartilage is the hallmark of various diseases, among which rheumatoid arthritis and osteoarthritis are the most prominent. Rheumatoid arthritis (RA) is a chronic joint degenerative disease, characterized by inflammation and destruction of the joint structures. When the disease is unchecked, it leads to substantial disability and pain due to loss of joint functionality and even premature death. The aim of an RA therapy, therefore, is not to slow down the disease but to attain remission in order to stop the joint destruction. Besides the severity of the disease outcome, the high prevalence of RA (˜0.8% of the adults are affected worldwide) means a high socio-economic impact. (For reviews on RA, we refer to Smolen and Steiner (2003); Lee and Weinblatt (2001); Choy and Panayi (2001); O'Dell (2004) and Firestein (2003)).

Osteoarthritis (also referred to as OA, or wear-and-tear arthritis) is the most common form of arthritis and is characterized by loss of articular cartilage, often associated with hypertrophy of the bone and pain. The disease mainly affects hands and weight-bearing joints such as knees, hips and spines. This process thins the cartilage. When the surface area has disappeared due to the thinning, a grade I osteoarthritis is reached; when the tangential surface area has disappeared, grade II osteoarthritis is reached. There are further levels of degeneration and destruction, which affect the deep and the calcified cartilage layers that border with the subchondral bone. For an extensive review on osteoarthritis, we refer to Wieland et al., 2005.

The clinical manifestations of the development of the osteoarthritis condition are: increased volume of the joint, pain, crepitation and functional disability that lead to pain and reduced mobility of the joints. When disease further develops, pain at rest emerges. If the condition persists without correction and/or therapy, the joint is destroyed leading to disability. Replacement surgery with total prosthesis is then required.

Therapeutic methods for the correction of the articular cartilage lesions that appear during the osteoarthritic disease have been developed, but so far none of them have been able to mediate the regeneration of articular cartilage in situ and in vivo.

Osteoarthritis is difficult to treat. At present, no cure is available and treatment focuses on relieving pain and preventing the affected joint from becoming deformed. Common treatments include the use of non-steroidal anti-inflammatory drugs (NSAIDs). Although dietary supplements such as chondroitin and glucosamine sulphate have been advocated as safe and effective options for the treatment of osteoarthritis, a recent clinical trial revealed that both treatments did not reduce pain associated to osteoarthritis. (Clegg et al., 2006). Taken together, no disease modifying osteoarthritic drugs are available.

In severe cases, joint replacement may be necessary. This is especially true for hips and knees. If a joint is extremely painful and cannot be replaced, it may be fused. This procedure stops the pain, but results in the permanent loss of joint function, making walking and bending difficult.

Another possible treatment is the transplantation of cultured autologous chondrocytes. Here, chondral cellular material is taken from the patient, sent to a laboratory where it is expanded. The material is then implanted in the damaged tissues to cover the tissue's defects.

Another treatment includes the intra-articular instillation of Hylan G-F 20 (e.g. Synvisc®, Hyalgan®, Artz®), a substance that improves temporarily the rheology of the synovial fluid, producing an almost immediate sensation of free movement and a marked reduction of pain.

Other reported methods include application of tendinous, periosteal, fascial, muscular or perichondral grafts; implantation of fibrin or cultured chondrocytes; implantation of synthetic matrices, such as collagen, carbon fiber; administration of electromagnetic fields. All of these have reported minimal and incomplete effects, resulting in a poor quality tissue that can neither support the weighted load nor allow the restoration of an articular function with normal movement.

Stimulation of the anabolic processes, blocking catabolic processes, or a combination of these two, may result in stabilization of the cartilage, and perhaps even reversion of the damage, and therefore prevent further progression of the disease. Various triggers may stimulate anabolic stimulation of chondrocytes. Insulin-like growth factor-I (IGF-I) is the predominant anabolic growth factor in synovial fluid and stimulates the synthesis of both proteoglycans and collagen. It has also been shown that members of the bone morphogenetic protein (BMP) family, notably BMP2, BMP4, BMP6, and BMP7, and members of the human transforming growth factor-β (TGF-β) family can induce chondrocyte anabolic stimulation (Chubinskaya and Kuettner, 2003). A compound has recently been identified that induces anabolic stimulation of chondrocytes (U.S. Pat. No. 6,500,854; EP 1 391 211). However, most of these compounds show severe side effects and, consequently, there is a strong need for compounds that stimulate chondrocyte differentiation without these side effects.

Vandeghinste et al. (WO 2005/124342) discovered JAK1 as a target whose inhibition might have therapeutic relevance for several diseases including OA. JAK1 belongs to the Janus kinase (JAK) family of cytoplasmic tyrosine kinases, involved in cytokine receptor-mediated intracellular signal transduction. The JAK family consists of 4 members: JAK1, JAK2, JAK3 and TYK2. JAKs are recruited to cytokine receptors, upon binding of the cytokine, followed by heterodimerization of the cytokine receptor and a shared receptor subunit (common gamma-c chain, gp130). JAKs are then activated by auto- and/or transphosphorylation by another JAK, resulting in phosphorylation of the receptors and recruitment and phosphorylation of members of the signal transducer and activator of transcription (STATs). Phosphorylated STATs dimerize and translocate to the nucleus where they bind to enhancer regions of cytokine-responsive genes. Knockout of the JAK1 gene in mice demonstrated that JAK1 plays essential and nonredundant roles during development: JAK1−/− mice died within 24 h after birth and lymphocyte development was severely impaired. Moreover, JAK1−/− cells were not, or less, reactive to cytokines that use class II cytokine receptors, cytokine receptors that use the gamma-c subunit for signaling and the family of cytokine receptors that use the gp130 subunit for signaling (Rodig et al., 1998).

Various groups have implicated JAK-STAT signaling in chondrocyte biology. Li et al. (2001) showed that Oncostatin M induces MMP and TIMP3 gene expression in primary chondrocytes by activation of JAK/STAT and MAPK signaling pathways. Osaki et al. (2003) showed that interferon-gamma mediated inhibition of collagen II in chondrocytes involves JAK-STAT signaling. IL1-beta induces cartilage catabolism by reducing the expression of matrix components, and by inducing the expression of collagenases and inducible nitric oxide synthase (NOS2), which mediates the production of nitric oxide (NO). Otero et al., (2005) showed that leptin and IL1-beta synergistically induced NO production or expression of NOS2 mRNA in chondrocytes, and that that was blocked by a JAK inhibitor. Legendre et al. (2003) showed that IL6/IL6Receptor induced downregulation of cartilage-specific matrix genes collagen II, aggrecan core and link protein in bovine articular chondrocytes, and that this was mediated by JAK/STAT signaling. Therefore, these observations suggest a role for JAK kinase activity in cartilage homeostasis and therapeutic opportunities for JAK kinase inhibitors.

JAK family members have been implicated in additional conditions including myeloproliferative disorders (O'Sullivan et al, 2007, Mol Immunol. 44(10):2497-506), where mutations in JAK2 have been identified. This indicates that inhibitors of JAK in particular JAK2 may also be of use in the treatment of myeloproliferative disorders. Additionally, the JAK family, in particular JAK1, JAK2 and JAK3, has been linked to cancers, in particular leukaemias e.g. acute myeloid leukaemia (O'Sullivan et al, 2007, Mol Immunol. 44(10):2497-506; Xiang et al., 2008, “Identification of somatic JAK1 mutations in patients with acute myeloid leukemia” Blood First Edition Paper, prepublished online Dec. 26, 2007; DOI 10.1182/blood-2007-05-090308) and acute lymphoblastic leukemia (Mullighan et al, 2009) or solid tumours e.g. uterine leiomyosarcoma (Constantinescu et al., 2007, Trends in Biochemical Sciences 33(3): 122-131), prostate cancer (Tam et al., 2007, British Journal of Cancer, 97, 378-383) These results indicate that inhibitors of JAK, in particular of JAK1 and/or JAK2, may also have utility in the treatment of cancers (leukaemias and solid tumours e.g. uterine leiomyosarcoma, prostate cancer).

In addition, Castleman's disease, multiple myeloma, mesangial proliferative glomerulonephritis, psoriasis, and Kaposi's sarcoma are likely due to hypersecretion of the cytokine IL-6, whose biological effects are mediated by intracellular JAK-STAT signaling (Tetsuji Naka, Norihiro Nishimoto and Tadamitsu Kishimoto, Arthritis Res 2002, 4 (suppl 3):S233-S242). This result shows that inhibitor of JAK, may also find utility in the treatment of said diseases.

A link with autoimmune diseases has been established for JAK3 and Tyk2. Mutations in JAK3 but also in the upstream signaling components gamma-c receptor chain and IL7 receptor account in aggregate for ˜70% of cases of human severe combined immunodeficiency ('OShea et al., 2004). Note that JAK1 cooperates with JAK3 in transducing signals from the gamma-c receptor chain. Tyk2 polymorphisms are seen in systemic lupus erythematosus (SLE) (O'Sullivan et al, 2007, Mol Immunol 44(10):2497-506). Hence, targeting the JAK family may provide a therapeutic opportunity in the immuno-inflammation area.

The current therapies are not satisfactory and therefore there remains a need to identify further compounds that may be of use in the treatment of diseases involving cartilage degradation, bone and/or joint degradation, for example osteoarthritis; and/or conditions involving inflammation or immune responses, such as Crohn's disease, rheumatoid arthritis, psoriasis, allergic airways disease (e.g. asthma, rhinitis), juvenile idiopathic arthritis, colitis, inflammatory bowel diseases, endotoxin-driven disease states (e.g. complications after bypass surgery or chronic endotoxin states contributing to e.g. chronic cardiac failure), diseases involving impairment of cartilage turnover (e.g diseases involving the anabolic stimulation of chondrocytes), congenital cartilage malformations, diseases associated with hypersecretion of IL6 and transplantation rejection (e.g. organ transplant rejection). Inhibitors of JAK can also find application in the treatment of proliferative diseases. In particular the inhibitors of JAK find application in the treatment of cancers, especially leukaemias and solid tumours (e.g. uterine leiomyosarcoma, prostate cancer). The present invention therefore provides compounds, methods for their manufacture and a pharmaceutical comprising a compound of the invention together with a suitable pharmaceutical carrier. The present invention also provides for the use of a compound of the invention in the preparation of a medicament for the treatment of degenerative joint diseases.

SUMMARY OF THE INVENTION

Similarly, reference to intermediates, whether or not they themselves are claimed, is meant to embrace their salts, and solvates, where the context so permits.

When ranges are referred to herein, for example but without limitation, C₁-C₈ alkyl, the citation of a range should be considered a representation of each member of said range.

Other derivatives of the compounds of this invention have activity in both their acid and acid derivative forms, but in the acid sensitive form often offers advantages of solubility, tissue compatibility, or delayed release in the mammalian organism (see, Bundgard, H., Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985). Prodrugs include acid derivatives well know to practitioners of the art, such as, for example, esters prepared by reaction of the parent acid with a suitable alcohol, or amides prepared by reaction of the parent acid compound with a substituted or unsubstituted amine, or acid anhydrides, or mixed anhydrides. Simple aliphatic or aromatic esters, amides and anhydrides derived from acidic groups pendant on the compounds of this invention are particularly useful prodrugs. In some cases it is desirable to prepare double ester type prodrugs such as (acyloxy)alkyl esters or ((alkoxycarbonyl)oxy)alkylesters. Particular such prodrugs are the C₁ to C₈ alkyl, C₂-C₈ alkenyl, aryl, C₇-C₁₂ substituted aryl, and C₇-C₁₂ arylalkyl esters of the compounds of the invention.

As used herein, the term ‘isotopic variant’ refers to a compound that contains unnatural proportions of isotopes at one or more of the atoms that constitute such compound. For example, an ‘isotopic variant’ of a compound can contain one or more non-radioactive isotopes, such as for example, deuterium (²H or D), carbon-13 (¹³C), nitrogen-15 (¹⁵N), or the like. It will be understood that, in a compound where such isotopic substitution is made, the following atoms, where present, may vary, so that for example, any hydrogen may be ²H/D, any carbon may be ¹³C, or any nitrogen may be ¹⁵N, and that the presence and placement of such atoms may be determined within the skill of the art. Likewise, the invention may include the preparation of isotopic variants with radioisotopes, in the instance for example, where the resulting compounds may be used for drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, i.e. ³H, and carbon-14, i.e. ¹⁴C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection. Further, compounds may be prepared that are substituted with positron emitting isotopes, such as ¹¹C, ¹⁸F, ¹⁵O and ¹³N, and would be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy.

All isotopic variants of the compounds provided herein, radioactive or not, are intended to be encompassed within the scope of the invention.

It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed ‘isomers’. Isomers that differ in the arrangement of their atoms in space are termed ‘stereoisomers’.

Stereoisomers that are not mirror images of one another are termed ‘diastereomers’ and those that are non-superimposable mirror images of each other are termed ‘enantiomers’. When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a ‘racemic mixture’.

‘Tautomers’ refer to compounds that are interchangeable forms of a particular compound structure, and that vary in the displacement of hydrogen atoms and electrons. Thus, two structures may be in equilibrium through the movement of π electrons and an atom (usually H). For example, enols and ketones are tautomers because they are rapidly interconverted by treatment with either acid or base. Another example of tautomerism is the aci- and nitro-forms of phenylnitromethane, that are likewise formed by treatment with acid or base.

Tautomeric forms may be relevant to the attainment of the optimal chemical reactivity and biological activity of a compound of interest.

The compounds of this invention may possess one or more asymmetric centers; such compounds can therefore be produced as individual (R)- or (S)-stereoisomers or as mixtures thereof.

Unless indicated otherwise, the description or naming of a particular compound in the specification and claims is intended to include both individual enantiomers and mixtures, racemic or otherwise, thereof. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art.

The Compounds

The present invention is based on the discovery that inhibitors of JAK are useful for the treatment of diseases involving cartilage degradation, bone and/or joint degradation, for example osteoarthritis; and/or conditions involving inflammation or immune responses, such as Crohn's disease, rheumatoid arthritis, psoriasis, allergic airways disease (e.g. asthma, rhinitis), juvenile idiopathic arthritis, colitis, inflammatory bowel diseases, endotoxin-driven disease states (e.g. complications after bypass surgery or chronic endotoxin states contributing to e.g. chronic cardiac failure), diseases involving impairment of cartilage turnover (e.g diseases involving the anabolic stimulation of chondrocytes), congenital cartilage malformations, diseases associated with hypersecretion of IL6 and transplantation rejection (e.g. organ transplant rejection). Inhibitors of JAK can also find application in the treatment of proliferative diseases. In particular the inhibitors of JAK find application in the treatment of cancers, especially leukaemias and solid tumours (e.g. uterine leiomyosarcoma, prostate cancer). In particular diseases involving cartilage degradation, bone and/or joint degradation and/or inflammation by administering a compound of the invention. The present compounds may be inhibitors of one or more members of the JAK family; specifically they may inhibit the activity of one or more of JAK1, JAK2, JAK3 and/or TYK2.

Pharmaceutical Compositions

When employed as pharmaceuticals, the compounds of the invention are typically administered in the form of a pharmaceutical composition. Such compositions can be prepared in a manner well known in the pharmaceutical art and comprise at least one active compound. Generally, the compounds of this invention are administered in a pharmaceutically effective amount. The amount of the compound actually administered will typically be determined by a physician, in the light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound-administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.

The pharmaceutical compositions of the invention can be administered by a variety of routes including oral, rectal, transdermal, subcutaneous, intra-articular, intravenous, intramuscular, and intranasal. Depending on the intended route of delivery, the compounds of this invention are preferably formulated as either injectable or oral compositions or as salves, as lotions or as patches all for transdermal administration

The compositions for oral administration can take the form of bulk liquid solutions or suspensions, or bulk powders. More commonly, however, the compositions are presented in unit dosage forms to facilitate accurate dosing. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient, vehicle or carrier. Typical unit dosage forms include prefilled, premeasured ampules or syringes of the liquid compositions or pills, tablets, capsules or the like in the case of solid compositions. In such compositions, the furansulfonic acid compound is usually a minor component (from about 0.1 to about 50% by weight or preferably from about 1 to about 40% by weight) with the remainder being various vehicles or carriers and processing aids helpful for forming the desired dosing form.

Liquid forms suitable for oral administration may include a suitable aqueous or nonaqueous vehicle with buffers, suspending and dispensing agents, colorants, flavors and the like. Solid forms may include, for example, any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring.

Injectable compositions are typically based upon injectable sterile saline or phosphate-buffered saline or other injectable carriers known in the art. As before, the active compound in such compositions is typically a minor component, often being from about 0.05 to 10% by weight with the remainder being the injectable carrier and the like.

Transdermal compositions are typically formulated as a topical ointment or cream containing the active ingredient(s), generally in an amount ranging from about 0.01 to about 20% by weight, preferably from about 0.1 to about 20% by weight, preferably from about 0.1 to about 10% by weight, and more preferably from about 0.5 to about 15% by weight. When formulated as a ointment, the active ingredients will typically be combined with either a paraffinic or a water-miscible ointment base. Alternatively, the active ingredients may be formulated in a cream with, for example an oil-in-water cream base. Such transdermal formulations are well-known in the art and generally include additional ingredients to enhance the dermal penetration of stability of the active ingredients or the formulation. All such known transdermal formulations and ingredients are included within the scope of this invention.

The compounds of this invention can also be administered by a transdermal device. Accordingly, transdermal administration can be accomplished using a patch either of the reservoir or porous membrane type, or of a solid matrix variety.

The above-described components for orally administrable, injectable or topically administrable compositions are merely representative. Other materials as well as processing techniques and the like are set forth in Part 8 of Remington's Pharmaceutical Sciences, 17th edition, 1985, Mack Publishing Company, Easton, Pa., which is incorporated herein by reference.

Biological Examples Example 1 In Vitro Assays Example 1.1 JAK1 Inhibition Assay

Recombinant human JAK1 catalytic domain (amino acids 850-1154; catalog number 08-144) was purchased from Carna Biosciences. 10 ng of JAK1 was incubated with 12.5 μg polyGT substrate (Sigma catalog number P0275) in kinase reaction buffer (15 mM Tris-HCl pH 7.5, 1 mM DTT, 0.01% Tween-20, 10 mM MgCl₂, 2 μM non-radioactive ATP, 0.25 μCi 33P-gamma-ATP (GE Healthcare, catalog number AH9968) final concentrations) with or without 5 μL containing test compound or vehicle (DMSO, 1% final concentration), in a total volume of 25 μL, in a polypropylene 96-well plate (Greiner, V-bottom). After 45 min at 30° C., reactions were stopped by adding of 25 μL/well of 150 mM phosphoric acid. All of the terminated kinase reaction was transferred to prewashed (75 mM phosphoric acid) 96 well filter plates (Perkin Elmer catalog number 6005177) using a cell harvester (Perkin Elmer). Plates were washed 6 times with 300 μL per well of a 75 mM phosphoric acid solution and the bottom of the plates was sealed. 40 μL/well of Microscint-20 was added, the top of the plates was sealed and readout was performed using the Topcount (Perkin Elmer). Kinase activity was calculated by subtracting counts per minute (cpm) obtained in the presence of a positive control inhibitor (10 μM staurosporine) from cpm obtained in the presence of vehicle. The ability of a test compound to inhibit this activity was determined as:

Percentage inhibition=((cpm determined for sample with test compound present−cpm determined for sample with positive control inhibitor) divided by (cpm determined in the presence of vehicle−cpm determined for sample with positive control inhibitor))*100%.

Dose dilution series were prepared for the compounds enabling the testing of dose-response effects in the JAK1 assay and the calculation of the IC₅₀ for each compound. Each compound was routinely tested at concentration of 20 μM followed by a 1/3 serial dilution, 8 points (20 μM-6.67 μM-2.22 μM-740 nM-247 nM-82 nM-27 nM-9 nM) in a final concentration of 1% DMSO. When potency of compound series increased, more dilutions were prepared and/or the top concentration were lowered (e.g. 5 μM, 1 μM).

The ability of a test compound to inhibit this activity was determined as:

Percentage inhibition=((cpm determined for sample with test compound present−cpm determined for sample with positive control inhibitor) divided by (cpm determined in the presence of vehicle−cpm determined for sample with positive control inhibitor))*100%.

Dose dilution series were prepared for the compounds enabling the testing of dose-response effects in the TYK2 assay and the calculation of the IC₅₀ for each compound. Each compound was routinely tested at concentration of 20 μM followed by a 1/3 serial dilution, 8 points (20M-6.67 μM-2.22 μM-740 nM-247 nM-82 nM-27 nM-9 nM) in a final concentration of 1% DMSO. When potency of compound series increased, more dilutions were prepared and/or the top concentration was lowered (e.g. 5 μM, 1 μM).

Example 2 Cellular Assays Example 2.1 JAK-STAT Signalling Assay

HeLa cells were maintained in Dulbecco's Modified Eagle's Medium (DMEM) containing 10% heat inactivated fetal calf serum, 100 U/mL penicillin and 100 μg/mL streptomycin. HeLa cells were used at 70% confluence for transfection. 20,000 cells in 87 μL cell culture medium were transiently transfected with 40 ng pSTAT1(2)-luciferase reporter (Panomics), 8 ng of LacZ reporter as internal control reporter and 52 ng of pBSK using 0.32 μL Jet-PEI (Polyplus) as transfection reagent per well in 96-well plate format. After overnight incubation at 37° C., 10% CO₂, transfection medium was removed. 75 μL of DMEM+1.5% heat inactivated fetal calf serum was added. 15 μL of compound at 6.7× concentration was added for 60 min and then 10 μL of human OSM (Peprotech) at 33 ng/mL final concentration.

All compounds were tested in duplicate starting from 20 μM followed by a 1/3 serial dilution, 8 doses in total (20 μM-6.6 μM-2.2 μM-740 nM-250 nM-82 nM-27 nM-9 nM) in a final concentration of 0.2% DMSO.

After overnight incubation at 37° C., 10% CO₂ cells were lysed in 100 μL lysis buffer/well (PBS, 0.9 mM CaCl₂, 0.5 mM MgCl2, 5% Trehalose, 0.025% Tergitol NP9, 0.15% BSA).

40 μL of cell lysate was used to read β-galactosidase activity by adding 180 μL βGal solution (30 μl ONPG 4 mg/mL+150 μL β-Galactosidase buffer (0.06 M Na₂HPO₄, 0.04 M NaH₂PO₄, 1 mM MgCl₂)) for 20 min. The reaction was stopped by addition of 50 μL Na₂CO₃ 1 M. Absorbance was read at 405 nm.

Luciferase activity was measured using 40 μL cell lysate plus 40 μl of Steadylite® as described by the manufacturer (Perkin Elmer), on the Envision (Perkin Elmer).

10 μM of a pan-JAK inhibitor was used as a positive control (100% inhibition). As negative control 0.5% DMSO (0% inhibition) was used. The positive and negative controls were used to calculate z’ and ‘percent inhibition’ (PIN) values.

Percentage inhibition=((fluorescence determined in the presence of vehicle−fluorescence determined for sample with test compound present) divided by (fluorescence determined in the presence of vehicle−fluorescence determined for sample without trigger))*100%.

PIN values were plotted for compounds tested in dose-response and EC₅₀ values were derived.

Example 2.2 OSM/IL-1β Signaling Assay

OSM and IL-1β were shown to synergistically upregulate MMP13 levels in the human chondrosarcoma cell line SW1353. The cells were seeded in 96 well plates at 15,000 cells/well in a volume of 120 μL DMEM (Invitrogen) containing 10% (v/v) FBS and 1% penicillin/streptomycin (InVitrogen) incubated at 37° C. 5% CO₂. Cells were preincubated with 15 μL compound in M199 medium with 2% DMSO 1 hr before triggering with 15 μL OSM and IL-1β to reach 25 ng/mL OSM and 1 ng/mL IL-1β, and MMP13 levels were measured in conditioned medium 48 hours after triggering. MMP13 activity was measured using an antibody capture activity assay. For this purpose, 384 well plates (NUNC, 460518, MaxiSorb black) were coated with 35 μL of a 1.5 μg/mL anti-human MMP13 antibody (R&D Systems, MAB511) solution for 24 hours at 4° C. After washing the wells 2 times with PBS+0.05% Tween, the remaining binding sites were blocked with 100 μL 5% non-fat dry milk (Santa Cruz, sc-2325, Blotto) in PBS for 24 hours at 4° C. Next, the wells were washed 2 times with PBS+0.05% Tween and 35 μL of 1/10 dilution of culture supernatant containing MMP13 in 100-fold diluted blocking buffer was added and incubated for 4 hours at room temperature. Next the wells were washed twice with PBS+0.05% Tween followed by MMP13 activation by addition of 35 μL of a 1.5 mM 4-Aminophenylmercuric acetate (APMA) (Sigma, A9563) solution and incubation at 37° C. for 1 hour. The wells were washed again with PBS+0.05% Tween and 35 μL MMP13 substrate (Biomol, P-126, OmniMMP fluorogenic substrate) was added. After incubation for 24 hours at 37° C. fluorescence of the converted substrate was measured in a Perkin Elmer Wallac EnVision 2102 Multilabel Reader (wavelength excitation: 320 nm, wavelength emission: 405 nm).

Example 2.3 PBL Proliferation Assay

Human peripheral blood lymphocytes (PBL) were stimulated with IL-2 and proliferation measured using a BrdU incorporation assay. The PBL were first stimulated for 72 hrs with PHA to induce IL-2 receptor, fasted for 24 hrs to stop cell proliferation followed by IL-2 stimulation for another 72 hrs (including 24 hr BrdU labeling). Cells were preincubated with test compounds 1 hr before IL-2 addition. Cells were cultured in RPMI 1640 containing 10% (v/v) FBS.

Example 3 In Vivo Models Example 3.1 CIA Model 3.1.1 Materials

Completed Freund's adjuvant (CFA) and incomplete Freund's adjuvant (IFA) were purchased from Difco. Bovine collagen type II (CII), lipopolysaccharide (LPS), and Enbrel were obtained from Chondrex (Isle d'Abeau, France); Sigma (P4252, L'Isle d'Abeau, France), Whyett (25 mg injectable syringe, France) Acros Organics (Palo Alto, Calif.), respectively. All other reagents used were of reagent grade and all solvents were of analytical grade.

3.1.2 Animals

Dark Agouti rats (male, 7-8 weeks old) were obtained from Harlan Laboratories (Maison-Alfort, France). Rats were kept on a 12 hours light/dark cycle (0700-1900). The temperature was maintained at 22° C., and food and water were provided ad libitum.

3.1.3 Collagen Induced Arthritis (CIA)

One day before the experiment, CII solution (2 mg/mL) was prepared with 0.05 M acetic acid and stored at 4° C. Just before the immunization, equal volumes of adjuvant (IFA) and CII were mixed by a homogenizer in a pre-cooled glass bottle in an ice water bath. Extra adjuvant and prolonged homogenization might be required if an emulsion is not formed. 0.2 mL of the emulsion was injected intradermally at the base of the tail of each rat on day 1, a second booster intradermal injection (CII solution at 2 mg/mL in CFA 0.1 mL saline) was performed on day 9. This immunization method was modified from published methods (Sims N A et al., (2004) Targeting osteoclasts with zoledronic acid prevents bone destruction in collagen-induced arthritis, Arthritis Rheum. 50 2338-2346; Jou et al., 2005).

3.1.4 Study Design

The therapeutic effects of the test compounds were tested in the rat CIA model. Rats were randomly divided into equal groups and each group contained 10 rats. All rats were immunized on day 1 and boosted on day 9. Therapeutic dosing lasted from day 16 to day 30. The negative control group was treated with vehicle (MC 0.5%) and the positive control group with Enbrel (10 mg/kg, 3× week., s.c.). A compound of interest was typically tested at 3 doses, e.g. 3, 10, 30 mg/kg, p.o.

3.1.5 Clinical Assessment of Arthritis

Arthritis was scored according the method of Khachigian 2006, Lin et al 2007 and Nishida et al. 2004. The swelling of each of the four paws was ranked with the arthritic score as follows: 0-no symptoms; 1-mild, but definite redness and swelling of one type of joint such as the ankle or wrist, or apparent redness and swelling limited to individual digits, regardless of the number of affected digits; 2-moderate redness and swelling of two or more types of joints; 3-severe redness and swelling of the entire paw including digits; 4-maximally inflamed limb with involvement of multiple joints (maximum cumulative clinical arthritis score 16 per animal) (Nishida et al., 2004).

3.1.6 Change in Body Weight (%) after Onset of Arthritis

Clinically, body weight loss is associated with arthritis (Shelton et al., 2005; Argiles et al., 1998; Rall, 2004; Walsmith et al., 2004). Hence, changes in body weight after onset of arthritis could be used as a non-specific endpoint to evaluate the effect of therapeutics in the rat model. The change in body weight (%) after onset of arthritis was calculated as follows:

${Mice}\text{:}\mspace{14mu} \frac{{{Body}\mspace{14mu} {Weight}_{({{week}\; 6})}} - {{Body}\mspace{14mu} {Weight}_{({{week}\; 5})}}}{{Body}\mspace{14mu} {Weight}_{({{week}\; 5})}} \times 100\%$ ${Rats}\text{:}\mspace{14mu} \frac{{{Body}\mspace{14mu} {Weight}_{({{week}\; 4})}} - {{Body}\mspace{14mu} {Weight}_{({{week}\; 3})}}}{{Body}\mspace{14mu} {Weight}_{({{week}\; 3})}} \times 100\%$

3.1.7 Radiology

X-ray photos were taken of the hind paws of each individual animal. A random blind identity number was assigned to each of the photos, and the severity of bone erosion was ranked by two independent scorers with the radiological Larsen's score system as follows: 0-normal with intact bony outlines and normal joint space; 1—slight abnormality with any one or two of the exterior metatarsal bones showing slight bone erosion; 2—definite early abnormality with any three to five of the exterior metatarsal bones showing bone erosion; 3—medium destructive abnormality with all the exterior metatarsal bones as well as any one or two of the interior metatarsal bones showing definite bone erosions; 4—severe destructive abnormality with all the metatarsal bones showing definite bone erosion and at least one of the inner metatarsal joints completely eroded leaving some bony joint outlines partly preserved; 5—mutilating abnormality without bony outlines. This scoring system is a modification from Salvcmini et al., 2001; Bush et al., 2002; Sims et al., 2004; Jou et al., 2005.

3.1.8 Histology

After radiological analysis, the hind paws of mice were fixed in 10% phosphate-buffered formalin (pH 7.4), decalcified with rapid bone decalcifiant for fine histology (Laboratories Eurobio) and embedded in paraffin. To ensure extensive evaluation of the arthritic joints, at least four serial sections (5 m thick) were cut and each series of sections were 100 m in between. The sections were stained with hematoxylin and eosin (H&E). Histologic examinations for synovial inflammation and bone and cartilage damage were performed double blind. In each paw, four parameters were assessed using a four-point scale. The parameters were cell infiltration, pannus severity, cartilage erosion and bone erosion. Scoring was performed as follows: 1-normal, 2-mild, 3-moderate, 4-marked. These four scores were summed together and represented as an additional score, namely the ‘RA total score’.

3.1.9 Micro-Computed Tomography (μCT) Analysis of Calcaneus (Heel Bone)

Bone degradation observed in RA occurs especially at the cortical bone and can be revealed by μCT analysis (Sims N A et al., 2004; Oste L et al., ECTC Montreal 2007). After scanning and 3D volume reconstruction of the calcaneus bone, bone degradation was measured as the number of discrete objects present per slide, isolated in silico perpendicular to the longitudinal axis of the bone. The more the bone that was degraded, the more discrete objects that were measured. 1000 slices, evenly distributed along the calcaneus (spaced by about 10.8 m), are analyzed.

3.1.10 Results

The following compounds were efficacious in all readouts performed in the rat CIA study, with statistical significance in several of the readouts: 18, 37, 145, 176, 200, 215, and 330.

Example 3.2 Septic Shock Model

Injection of lipopolysaccharide (LPS) induces a rapid release of soluble tumour necrosis factor (TNF-alpha) into the periphery. This model is used to analyse prospective blockers of TNF release in vivo.

Six BALB/cJ female mice (20 g) per group were treated at the intended dosing once, po. Thirty minutes later, LPS (15 μg/kg; E. Coli serotype 0111:B4) was injected ip. Ninety minutes later, mice were euthanized and blood was collected. Circulating TNF alpha levels were determined using commercially available ELISA kits. Dexamethasone (5 μg/kg) was used as a reference anti-inflammatory compound. Selected compounds are tested at one or multiple doses, e.g. 3 and/or 10 and/or 30 mg/kg, po.

The following compounds exhibited a statistically significant reduction in the TNF release (>50%) at 30 mg/kg po: 12, 18, 36, 37, 52, 60, 74, 125, 148, 176, 197, 200, 207, 208, 215, and 229.

Example 3.3 MAB Model

The MAB model allows a rapid assessment of the modulation of an RA-like inflammatory response by therapeutics (Kachigian L M. Nature Protocols (2006) 2512-2516: Collagen antibody-induced arthritis). DBA/J mice were injected i.v. with a cocktail of mAbs directed against collagen II. One day later, compound treatment was initiated (vehicle: 10% (v/v) HPβCD). Three days later, mice received an i.p. LPS injection (50 μg/mouse), resulting in a fast onset of inflammation. Compound treatment was continued until 10 days after the mAb injection. Inflammation was read by measuring paw swelling and recording the clinical score of each paw. The cumulative clinical arthritis score of four limbs was presented to show the severity of inflammation. A scoring system is applied to each limb using a scale of 0-4, with 4 being the most severe inflammation.

-   -   0 Symptom free     -   1 Mild, but definite redness and swelling of one type of joint         such as the ankle or wrist, or apparent redness and swelling         limited to individual digits, regardless of the number of         affected digits     -   2 Moderate redness and swelling of two or more types of joints     -   3 Severe redness and swelling of the entire paw including digits     -   4 Maximally inflamed limb with involvement of multiple joints

The following compound, dosed p.o. at 30 mg/kg reduced the clinical score with statistical significance at 30 mg/kg and significantly reduced inflammation at 30 mg/kg doses: 36, 37, 176

Example 4 Toxicity, DMPK and Safety Models Example 4.1 Thermodynamic Solubility

A solution of 1 mg/mL of the test compound is prepared in a 0.2M phosphate buffer pH7.4 or a 0.1M citrate buffer pH3.0 at room temperature in a glass vial.

The samples are rotated in a Rotator drive STR 4 (Stuart Scientific, Bibby) at speed 3.0 at room temperature for 24 hours.

After 24 hours, 800 μL of the sample is transferred to an eppendorf tube and centrifuged 5 min at 14000 rpm. 200 μL of the supernatant of the sample is then transferred to a MultiscreenR Solubility Plate (Millipore, MSSLBPC50) and the supernatant is filtered (10-12″ Hg) with the aid of a vacuum manifold into a clean Greiner polypropylene V-bottom 96 well plate (Cat no. 651201). 5 μL of the filtrate is diluted into 95 μL (F20) of the same buffer used to incubate in the plate containing the standard curve (Greiner, Cat no. 651201).

The standard curve for the compound is prepared freshly in DMSO starting from a 10 mM DMSO stock solution diluted factor 2 in DMSO (5000 μM) and then further diluted in DMSO up to 19.5 μM. 3 μl of the dilution series as from 5000 μM is then transferred to a 97 μl acetonitrile-buffer mixture (50/50). The final concentration range was 2.5 to 150 μM.

The plate is sealed with sealing mats (MA96RD-04S, www.kinesis.co.uk) and samples are measured at room temperature on LCMS (ZQ 1525 from Waters) under optimized conditions using Quanoptimize to determine the appropriate mass of the molecule.

The samples are analyzed on LCMS with a flow rate of 1 ml/min. Solvent A is 15 mM ammonia and solvent B is acetonitrile. The sample is run under positive ion spray on an XBridge C18 3.5 μM (2.1×30 mm) column, from Waters. The solvent gradient has a total run time of 2 minutes and ranges from 5% B to 95% B.

Peak areas are analyzed with the aid of Masslynx software package and peak areas of the samples are plotted against the standard curve to obtain the solubility of the compound.

Solubility values are reported in μM or μg/mL.

Example 4.2 Aqueous Solubility

Starting from a 10 mM stock in DMSO, a serial dilution of the compound is prepared in DMSO. The dilution series is transferred to a 96 NUNC Maxisorb plate F-bottom (Cat no. 442404) and 0.2M phosphate buffer pH7.4 or 0.1M citrate buffer pH3.0 at room temperature is added.

The final concentration ranges from 200 μM to 2.5 μM in 5 equal dilution steps. The final DMSO concentration does not exceed 2%. 200 μM Pyrene is added to the corner points of each 96 well plate and serves as a reference point for calibration of Z-axis on the microscope.

The assay plates are sealed and incubated for 1 hour at 37° C. while shaking at 230 rpm. The plates are then scanned under a white light microscope, yielding individual pictures of the precipitate per concentration. The precipitate is analyzed and converted into a number which was plotted onto a graph. The first concentration at which the compound appears completely dissolved is the concentration is reported, however the true concentration lies somewhere between this concentration and one dilution step higher.

Solubility values are reported in μg/mL.

Example 4.3 Plasma Protein Binding (Equilibrium Dialysis)

A 10 mM stock solution of the compound in DMSO is diluted with a factor 5 in DMSO. This solution is further diluted in freshly thawed human, rat, mouse or dog plasma (BioReclamation INC) with a final concentration of 10 μM and final DMSO concentration of 0.5% (5.5 μl in 1094.5 μl plasma in a PP-Masterblock 96 well (Greiner, Cat no. 780285))

A Pierce Red Device plate with inserts (ThermoScientific, Cat no. 89809) is prepared and filled with 750 μL PBS in the buffer chamber and 500 μL of the spiked plasma in the plasma chamber. The plate is incubated for 4 hours at 37° C. while shaking at 230 rpm. After incubation, 120 μL of both chambers is transferred to 360 μL acetonitrile in a 96-well round bottom, PP deep-well plates (Nunc, Cat no. 278743) and sealed with an aluminum foil lid. The samples are mixed and placed on ice for 30 min. This plate is then centrifuged 30 min at 1200 rcf at 4° C. and the supernatant is transferred to a 96 v-bottom PP plate (Greiner, 651201) for analysis on LCMS.

The plate is sealed with sealing mats (MA96RD-04S) of www.kinesis.co.uk and samples are measured at room temperature on LCMS (ZQ 1525 from Waters) under optimized conditions using Quanoptimize to determine the appropriate mass of the molecule.

The samples are analyzed on LCMS with a flow rate of 1 mL/min. Solvent A was 15 mM ammonia and solvent B was acetonitrile. The sample was run under positive ion spray on an XBridge C18 3.5 μM (2.1×30 mm) column, from Waters. The solvent gradient has a total run time of 2 minutes and ranges from 5% B to 95% B.

Peak area from the compound in the buffer chamber and the plasma chamber are considered to be 100% compound. The percentage bound to plasma is derived from these results and is reported to the LIMS as percentage bound to plasma.

The solubility of the compound in the final test concentration in PBS is inspected by microscope to indicate whether precipitation is observed or not.

The internal patch pipette solution contains: 100 mM Kgluconate, 20 mM KCl, 1 mM CaCl₂, 1 mM MgCl₂, 5 mM Na₂ATP, 2 mM Glutathione, 11 mM EGTA, 10 mM HEPES, pH 7.2.

Drugs are perfused using a Biologic MEV-9/EVH-9 rapid perfusion system.

All recordings are performed on HEK293 cells stably expressing hERG channels. Cells are cultured on 12 mm round coverslips (German glass, Bellco) anchored in the recording chamber using two platinum rods (Goodfellow). hERG currents are evoked using an activating pulse to +40 mV for 1000 ms followed by a tail current pulse to −50 mV for 2000 ms, holding potential was −80 mV. Pulses are applied every 20 s and all experiments are performed at room temperature.

4.4.2 Data Analysis

IC₅₀ and IC₂₀ values are calculated for each compound tested. The fold difference between the IC₂₀ and the unbound C_(max) concentrations of the test compound obtained at relevant therapeutic doses as determined by results obtained from the rat CIA model is calculated.

For the concentration response curves, peak tail current amplitude is measured during the voltage step to −50 mV. Curve-fitting of concentration-response data is performed using the equation:

y=a+[(b−a)/(1+10̂((log c−x)d)]

where a is minimum response, b is maximum response and d is Hill slope, this equation can be used to calculate both IC₅₀ (where y=50 and c is the IC₅₀ value) and IC₂₀ (where y=20 and c is the IC₂₀ value). GraphPad® Prism® (Graphpad® Software Inc.) software is used for all curve fitting.

A difference of 100 fold or greater indicates a low potential for QT prolongation.

Example 4.5 Microsomal Stability

A 10 mM stock solution of compound in DMSO was diluted 1000 fold in a 182 mM phosphate buffer pH7.4 in a 96 deep well plate (Greiner, Cat no. 780285) and pre-incubated at 37° C.

40 μL of deionised water was added to a well of a polypropylene Matrix 2D barcode labelled storage tube (Thermo Scientific) and pre-incubated at 37° C.

A Glucose-6-phosphate-dehydrogenase (G6PDH) working stock solution was prepared in 182 mM phosphate buffer pH7.4 and placed on ice before use. A. co-factor containing MgCl2, glucose-6-phosphate and NADP+ was prepared in deionised water and placed on ice before use.

A final working solution containing liver microsomes (Xenotech of a species of interest (human, mouse, rat, dog), previously described G6PDH and co-factors was prepared and this mix was incubated for no longer than 20 minutes at room temperature.

30 μL of the pre-heated compound dilution was added to 40 μL of pre-heated water in the Matrix tubes and 30 μL of the microsomal mix was added. Final reaction concentrations were 3 μM compound, 1 mg microsomes, 0.4 U/mL GDPDH, 3.3 mM MgCl₂, 3.3 mM glucose-6-phosphate and 1.3 mM NADP+.

To measure percentage remaining of compound at time zero MeOH or ACN was added (1:1) to the well before adding the microsomal mix. The plates were sealed with Matrix Sepra Seals™ (Matrix, Cat. No. 4464) and shaken for a few seconds ensure complete mixing of all components.

The samples which were not stopped are incubated at 37° C., 300 rpm and after 1 hour of incubation the reaction was stopped with MeOH or ACN (1:1).

After stopping the reaction the samples were mixed and placed on ice for 30 min to precipitate the proteins. The plates were then centrifuged 30 min at 1200 rcf at 4° C. and the supernatant was transferred to a 96 v-bottom PP plate (Greiner, 651201) for analysis on LCMS.

These plates were sealed with sealing mats (MA96RD-04S) of www.kinesis.co.uk and samples were measured at room temperature on LCMS (ZQ 1525 from Waters) under optimized conditions using Quanoptimize to determine the appropriate mass of the parent molecule.

The samples were analyzed on LCMS with a flow rate of 1 mL/min. Solvent A was 15 mM ammonia and solvent B was methanol or acetonitrile, depending on the stop solution used. The samples were run under positive ion spray on an XBridge C18 3.5 μM (2.1×30 mm) column, from Waters. The solvent gradient had a total run time of 2 minutes and ranges from 5% B to 95% B. Peak area from the parent compound at time 0 was considered to be 100% remaining. The percentage remaining after 1 hour incubation was calculated from time 0 and was calculated as the percentage remaining. The solubility of the compound in the final test concentration in buffer is inspected by microscope and results are reported.

The data on microsomal stability are expressed as a percentage of the total amount of compound remaining after 60 minutes.

Example 4.6 Caco2 Permeability

Bi-directional Caco-2 assays were performed as described below. Caco-2 cells were obtained from European Collection of Cell Cultures (ECACC, cat 86010202) and used after a 21 day cell culture in 24-well Transwell plates (Fisher TKT-545-020B).

2×10⁵ cells/well were seeded in plating medium consisting of DMEM+GlutaMAXI+1% NEAA+10% FBS (FetalClone II)+1% Pen/Strep. The medium was changed every 2-3 days.

Test and reference compounds (propranolol and rhodamine123 or vinblastine, all purchased from Sigma) were prepared in Hanks' Balanced Salt Solution containing 25 mM HEPES (pH7.4) and added to either the apical (125 μL) or basolateral (600 μL) chambers of the Transwell plate assembly at a concentration of 10 μM with a final DMSO concentration of 0.25%.

50 μM Lucifer Yellow (Sigma) was added to the donor buffer in all wells to assess integrity of the cell layers by monitoring Lucifer Yellow permeation. As Lucifer Yellow (LY) cannot freely permeate lipophilic barriers, a high degree of LY transport indicates poor integrity of the cell layer.

After a 1 hour incubation at 37° C. while shaking at an orbital shaker at 150 rpm, 70 μL aliquots were taken from both apical (A) and basal (B) chambers and added to 100 μL1 50:50 acetonitrile:water solution containing analytical internal standard (0.5 μM carbamazepine) in a 96 well plate.

Lucifer yellow was measured with a Spectramax Gemini XS (Ex 426 nm and Em 538 nm) in a clean 96 well plate containing 150 μL of liquid from basolateral and apical side.

Concentrations of compound in the samples were measured by high performance liquid-chromatography/mass spectroscopy (LC-MS/MS).

Apparent permeability (P_(app)) values were calculated from the relationship:

P _(app)=[compound]_(acceptor final) ×V _(acceptor)/([compound]_(donor initial) ×V _(donor))/T _(inc) ×V _(donor)/surface area×60×10⁻⁶ cm/s

V=chamber volume T_(inc)=incubation time. Surface area=0.33 cm²

The Efflux ratios, as an indication of active efflux from the apical cell surface, were calculated using the ratio of P_(app)B>A/P_(app)A>B.

The following assay acceptance criteria were used:

Propranolol: P_(app) (A>B) value>20(×10⁻⁶ cm/s) Rhodamine 123 or Vinblastine: P_(app) (A>B) value<5(×10⁻⁶ cm/s) with Efflux ratio≧5. Lucifer yellow permeability: ≦100 nm/s

Example 4.7 Pharmacokinetic Study in Rodents 3.1.3 Pharmacokinetic Study

Compounds are formulated in PEG200/physiological saline or PEG400/DMSO/physiological saline mixtures for the intravenous route and in 0.5% methylcellulose or 10-30% hydroxylpropyl-P-cyclodextrine pH3 or pH7.4 for the oral route. Test compounds are orally dosed as a single esophageal gavage at 5-10 mg/kg and intravenously dosed as a bolus via the caudal vein at 1 mg/kg. Each group consists of 3 rats. Blood samples are collected either via the jugular vein using cannulated rats or at the retro-orbital sinus with lithium heparin as anti-coagulant at the time points in the following range: 0.05 to 8 hours (intravenous route), and 0.25 to 6 or 24 hours (oral route). Whole blood samples are centrifuged at 5000 rpm for 10 min and the resulting plasma samples are stored at −20° C. pending analysis.

3.1.4 Quantification of Compound Levels in Plasma

Plasma concentrations of each test compound are determined by an LC-MS/MS method in which the mass spectrometer was operated in positive electrospray mode.

3.1.5 Determination of Pharmacokinetic Parameters

Pharmacokinetic parameters are calculated using Winnonlin® (Pharsight®, United States).

Example 4.8 7-Day Rat Toxicity Study

A 7-day oral toxicity study with test compounds is performed in Sprague-Dawley male rats to assess their toxic potential and toxicokinetics, at daily doses of 100, 300 and 500 mg/kg/day, by gavage, at the constant dosage-volume of 5 mL/kg/day.

The test compounds are formulated in 30% (v/v) HPβCD in purified water. Each group included 5 principal male rats as well as 3 satellite animals for toxicokinetics. A fourth group is given 30% (v/v) HPβCD in water only, at the same frequency, dosage volume and by the same route of administration, and acted as the vehicle control group.

The goal of the study is to determine the lowest dose that resulted in no adverse events being identified (no observable adverse effect level—NOAEL).
